Four Colorado high school students are protesting after an advisor insisted they remove a photo of a lesbian couple from their yearbook.

Rudolpho Tribulio and Anna Carmichael, students at Palmer High School in Colorado, told KRDO-TV on Monday that their advisor ordered that they cut the photo of the couple holding hands from their "relationships" section of the book. The students said they were removed from the yearbook staff because of the dispute. Two other students subsequently quit the yearbook staff.

"She told me to in these exact words, you either cut the gay couple or I cut the page," Tribulio told KRDO-TV.

School District 11 backed the Palmer High School yearbook advisor's decision to cut the photo.

"When the photos came back from that page there was too much PDA and that is against Palmer policy," said spokeperson Devra Ashby to KRDO-TV. "Regardless of any sort of situation inside the photograph. If there's too much PDA, it's against policy. It's going to get cut."

KRDO-TV said that last year's yearbook included photos with several forms of public displays of affection.

Not only did the advisor cut the photo, she also cut the "relationship" page altogether, replacing it with a "diversity" page. But Carmichael said the "diversity" page also had some restrictions.

"No names, only the labels. So for a picture of a Muslim, she wanted to label them as a Muslim," said Carmichael, the yearbook's former editor.

In 2010, a high school yearbook staff in Mississippi cut the senior portrait of Cearra Sturgis, a lesbian who wore a tuxedo in her photo. In a settlement, Copiah County School District agreed to to drop gender-specific outfits for senior portraits and instead require all students to wear a cap and gown, according to msnbc.com.

In January, another Colorado high school student's photos were rejected from the yearbook, this time for being "inappropriate" and "unprofessional." In one photo, Sydney Spies, an 18-year-old aspiring model, was wearing a short yellow skirt and a black shawl that exposed her shoulders and midsection.

"I feel like they aren't allowing me to have my freedom of expression," Spies told the Durango Herald.

What do you think? Should School District 11 allow the photo of the lesbian couple in the yearbook?
